Newbie needs help on Audio Research and DynAudio Quality


Hello all,

 

I am a newbie to high end home audio and need help from all of you audiophiles out there. I was actually into high end car audio back to when I was younger so I kinda understand what sound quality level can be considered at audiophile standard. I bought this set up (2 mono amps Audio Research Classic 120, Audio Research LS22 preamp, Dynaudio Contour 1.8 mkII, Rega Planet CD player) 4 years ago and did not have time and room to put them up to enjoy until recently. After setting them up last week, I was very disappointed at the performance. The sound was harsh and I would get tired after listening to 2-3 songs. I remember when I picked up the speakers, the previous owner played a couple of songs using his turntable and it was warm, clear and enjoyable (I could not remember what equipment he had back then). I have another set of solid state stuff to play around which includes Luxman M-12 amplifier, Sansui CA-2000 preamp, JBL 4311B, and same CD player Rega Planet. The sound quality is much better compared to ARC set. I expect that the ARC set at least has to be at entry level of audiophile but what I got out from it is disappointing. I need help from you experts to point out what is wrong or what I should expect from Audio Research.

Best Regards,

Dan

The LS-22 is one of the very few ARC preamps I’ve ever heard criticized in the forums (many years ago) as mediocre. Suggest replacing it with an Ref-3, Ref-5SE, even an LS-2B.
I’ve owned a number of ARC units and hold them in high regard.
Also, what wire are you using? I use OCC copper exclusively (YMMV).

"Also, I checked and see one of the big tubes in one of the amp is not lighting up."

I am surprised that the amp plays anything if an output tube is bad/blown, my Classic 150 will go into protection mode (indicated by dimming of Screen LED).

The Classic 150 has a 7 position terminal block on the rear with taps from the output transformer connected to it internally, see your owner's manual for the 4 ohm terminal combination.

My Dynaudio Mirage were 4 ohm and I had no issues as I stated above 

Good luck

Had an LS22 in my room to compare to my LS2BMKII (stock 25 year old) preamp.  The LS 22 went back, not even close.

I'm a little surprised no one has mentions the Rega CD Player.  You could have the best equipment in the world strung together and if the source component isn't on the same level it'll just sound like a common stereo.  I suggest that you not rule out the culprit as being the CD Player.
